The police label of 'accidental drowning' does more than set tongues wagging in the small Missouri town of Klim; it starts an avalanche of cancellations that threaten to sink Rona Murray's bakery business. And blacken her good name. Determined to keep both afloat, she starts her own investigation to prove she and her property are blameless.  Her ex-husband, Johnny, at times helps and hinders her detective work, which raises her suspicion about his sudden reappearance in her life.  Ditto for his current girlfriend, Crystal, who's two-timing him with Rona's bad boy neighbor, Frank. Crystal knew the drowned woman, but is there a motive for murder in that friendship? Or does it buoy up Rona's misgivings of Frank and Johnny? Her mistrust seems to hold water when she discovers property vandalism and midnight lights in the woods—both of which escalate into a struggle against life and death in a raging river.
